Every year lakhs of young minds apply for NDA and CDS examinations to become commissioned officers in the Indian Army. Also, many former NDA aspirants sit for graduate entries to wear the olive greens. However, they often get involved in the NDA vs CDS SSB debate.
If you are someone who feels that the CDS SSB is more difficult than that for NDA, we debunk all your myths today.
NDA vs CDS SSB: What it Means
Before diving into the pool of the debate, let us look into the meaning of NDA vs CDS SSB.
The National Defence Academy (NDA) exam is only open to 10+2 candidates, who can apply to either of the tri-services through it. Those who clear it get their call letters for the SSB interview. Such an entry is called NDA SSB entry.

The CDSE SSB entry requires graduates to clear the Combined Defence Services Examination (CDSE). The UPSC conducts both exams, however, the scheme of examination is different.
| EXAM | SYLLABUS | MARKING SCHEME |
| NDA | I: GAT II: Mathematics | 600 marks 300 marks |
| CDSE | I: English II: GS III: Elementary Maths* | 100 marks 100 marks 100 marks |
*The Maths paper in CDSE is only for IMA, AFA, and INA optees.
Basic Differences
Now that you know the meaning of both the entries, here are some basic differences that you must be aware of between the two entries:
| NDA Entry | CDS Entry |
| 1. Stands for National Defence Academy Exam | 1. Stands for Combined Defence Services Exam |
| 2. Same written exam for all services | 2. Maths is only for male candidates opting for IMA, AFA, or INA |
| 3. Permanent commission (PC) | 3. PC for IMA, AFA, and INA SSC for OTA |
| 4. Age bracket: 16.6 to 19.5 years | 4. Age bracket: 19 to 24 years |
| 5. 3 years of training at NDA+1 year of training at service academy | 5. 1 to 1.5 years of training at service academy |
This table makes the NDA vs CDS SSB comparison easier for candidates. Each entry is special int its own way.
NDA vs CDS SSB?
As we’ve shown above, NDA is for 10+2 candidates who are in their teenage and are just developing their morals and thought process. However, CDS entry candidates are graduates with well-developed thinking and ideas due to their exposure.

Hence, the only thing that marks the NDA vs CDS SSB debate is how each entry’s candidates are assessed. Since 10+2 candidates are younger, they often get leeway in certain areas such as:
- Clarity of career choice
- Handling setbacks or personal issues
- Responsibility towards others and leadership
- Social maturity
If an NDA candidate wants to join the Indian Army for adventure, it is generally acceptable. However, this cannot be the only reason for a CDS candidate.
The level of maturity and reasoning in CDS SSB candidates must be higher than NDA candidates. It is just a way for adjusting to the different stages of life that they’re coming from.
Please know that there is no compromise in the 15 OLQs that the assessors want, but the goalpost for NDA vs CDS SSB may be moved slightly by them, depending on which age group is under assessment.
